European style options trade in the US. Use any broker. Or are you referring to options on European companies? Mark
How is the daily volume for US Weekly options (SPX) traded in the US? because on Ameritrade there is no mention for the open interest and daily traded contracts
For June 11 SPY options; those weekly options do they expire in morning or evenings? Last time to trade is on Thursday evening or Friday morning? Sorry for the trivial question!
For options on SPY (ETF) the last trading day is Friday, so you can trade them till Friday's close. See here for the OCC memo. By the way, it took me 5 seconds to find this memo using Google.
